Diane Lane would be the most likely candidate. I've been told I look like Marg Helgenberger (Catherine Willows on CSI) and Michelle Pfeiffer as well (TOTALLY don't see that one myself). But as far as personality, I'd like Buffy the Vampire Slayer to play me.
Jennifer Garner, Reese Witherspoon, or Naomi Watts.
These actresses are yummy mummies on the red carpet and slummy mummies with the kiddies. I do not mean that they look slummy or gross, but that they are not beautiful all the time when taking care of their kids. They look like the mom you know down the street. This is real life! http://lamomparis.blogspot.com/
Meg Ryan in the When Harry Met Sally era. She's quirky and funny and has that wild (permed, I assume) hair. My hair has gone from stick straight to crazy curly since the birth of my two kiddos, so we have that physically in common - if nothing else!.
it would be Michelle Yeoh 'cos we're both Malaysians. We live in the same town and were classmates back in the 70's. This could be her most challenging role as she's known for her butt-kicking and sword-wielding action !
